Contraceptive system and method of use

a contraceptive and occluding member technology, applied in the field of contraceptives and sterilization devices, can solve the problems of inability to secure the cost and attendant risks of surgery, and the inability to control the hormone level of the drug strategy, so as to facilitate the securing of prevent the passage of reproductive cells, and facilitate the effect of securing the expanded occluding member

Benefits of technology

Provides effective and reversible contraception for both males and females with minimal invasive procedures, ensuring safety and ease of use through the use of catheters and guidewires.

Problems solved by technology

While each have certain advantages, they also suffer from various drawbacks.
Barriers such as condoms and diaphragms are subject to failure due to breakage and displacement.
Drug strategies, such as the pill and Norplant™, which rely on artificially controlling hormone levels, suffer from known and unknown side-effects from prolonged use.
Finally, surgical procedures, such as tubal ligation and vasectomy, involve the costs and attendant risks of surgery, and are frequently not reversible.

Embodiment Construction

[0026]FIG. 1 illustrates a catheter 10 useful in the practice of the invention, which comprises an elongated shaft 12 having an inflation lumen 14 which is in fluid communication with inflatable member 16 mounted on a distal section of the catheter shaft and adapter 18. Occluding member 20, a self-supporting metallic member of shape-memory material, closely conforms to the diameter of the uninflated inflatable member 16 to facilitate introduction into the desired body lumen. Occluding member 20 is formed so that it has a remembered collapsed configuration with relatively small transverse dimensions. The occluding member 20 may be deformed to facilitate mounting onto the inflatable member 16 and is expanded by the inflatable member to an open expanded configuration within a body lumen. Upon heating to a transition temperature it will revert to the remembered configuration. In this embodiment the occluding member 20 has an open, lattice-type structure facilitating endothelialization w...

Abstract

A device and method of using the device for contraception or sterilization and particularly for reversible contraception by occluding a reproductive lumen to prevent the passage of reproductive cells through the lumen for a desired period of time until the patient wishes to become fertile again and then be reopened. The occluding member preferably comprises a tubular framework formed from a shape memory material configured to be implanted in a reproductive lumen. The occluding member is implanted within a body lumen, secured to the wall of the reproductive lumen and then collapsed to collapse the wall and occlude the lumen. Alternatively, the occluding member may be collapsed upon a solid plug. The closure of the reproductive lumen may be reversed by introducing a balloon catheter and by a series of inflations of the balloon reexpanding the collapsed occluding member or by removing the plug. The occluding member and the plug may be configured to facilitate endothelialization, to provoke an inflammatory responses or to deliver a drug.

Description

FIELD OF INVENTION[0001]This invention relates to the field of contraceptive and sterilization devices and more particularly to reversible contraceptive devices and the methods of using such devices.BACKGROUND OF THE INVENTION[0002]Conventional contraceptive strategies generally fall within three categories: physical barriers, drugs and surgery. While each have certain advantages, they also suffer from various drawbacks. Barriers such as condoms and diaphragms are subject to failure due to breakage and displacement. Drug strategies, such as the pill and Norplant™, which rely on artificially controlling hormone levels, suffer from known and unknown side-effects from prolonged use. Finally, surgical procedures, such as tubal ligation and vasectomy, involve the costs and attendant risks of surgery, and are frequently not reversible. Thus, there remains a need for a safe, effective method of contraception, particularly a non-surgical method which is reversible.SUMMARY OF THE INVENTION[0...
